Researchers have reexamined the skull musculature of coelacanths, a lineage of fish dating back 400 million years, and discovered that many anatomical structures had been previously misidentified. The coelacanth, often called a “living fossil,” has remained anatomically similar for over 65 million years. While it is one of the most extensively examined fish in scientific […]



Summary

A new study re-evaluating coelacanth skull musculature reveals widespread misidentification of anatomical structures. Despite being a well-studied “living fossil” with a stable anatomy for 65 million years, the coelacanth’s skull has been misunderstood. This research provides a more accurate anatomical description of this ancient fish, offering insights into its evolutionary history and the evolution of vertebrate head anatomy. The findings highlight the importance of re-examining established anatomical knowledge, even in seemingly well-understood organisms.
